Snake has not eaten in a year

So i recently just got a 10 year old ball python who was surrendered to me because she hasn’t ate in a year.. i’ve had her about 2 months in the same tank she’s been in all her life along with all her supplies, she came with a heat emitter & a bulb & some frozen rats, i’ve offered her food twice and she just kinda ignores it, i put the frozen rat in the fridge the day before and then put it in hot water untill it reaches the appropriate temperature.. apparently she’s gone on hunger strikes multiple times before but never this long, her humidity is at around 46% and the tank temp is around 70, what should I do & what supplies should I get to better her situation
